Lever 6 turns about fixed axis A and is connected by turning pairs B and C to links 11 and 12, which, in turn, are connected by turning pairs D and E to bellows 7 and to piston 5. When the pressure increases in pipeline 1, membrane 2 is bent to the left and diverts jet valve nozzle 3 opposite the left-hand channel so that fluid from the nozzle is delivered to the upper end of the servomotor cylinder. Piston 5 moves downwar and closes valve 4 to some extent. At the same time, link 11 compresses bellows 7. The system consisting of two bellows, 7 and 8, is filled with fluid and is airtight. The chamber of bellows 8 is connected through flow-control valve 10 to a vessel containing the fluid. When bellows 7 is compressed, the pressure in its chamber increases and this compresses bellows 8 which, through spring 9, diverts jet nozzle 3 to the right. When the bellows are deformed, the pressure of the fluid in them is increased, so that part of the fluid escapes through flow-control valve 10 and jet nozzle 3 returns to its initial position. When the pressure decreases in pipeline 1, the elements of the regulator operate in the reverse direction.
